Inventor: HAHN RICHARD
IPC: A63B51/005
Filed: 1979-04-25
Abstract: The device is for resting the tension of tennis racquet string has a press plate acting on the strings in a direction perpendicular to the plane of the strings. A lever system applies a definite fore to the plate which deforms according to the tension. The plate deflection is transferred to a tension indicator (12) via a measurement rod. It performs accurate testing of all current racquet types. The transfer ratio of the lever is variable and is displayed on a second scale (11). The device has four racquet frame resting points (2, 3) one (3) of which is adjustable for height. The pressure plate is connected via a parallel linkage guide (5-8) with a fixed part carrying the scale. The plate force is varied by moving the weight (10) perpendicular to the guide rotation axis.

Title: Process-controlled timber seasoning chamber - has humidity and temp. cycles controlled to suit inherent measured humidity in timber stack
Inventor: KRAEMER HELMUT DIPL ING
IPC: F26B25/22
Filed: 1979-04-30
Abstract: A drying room for timber has the process controlled to reduce the humidity such that large variations across the product stack may be tolerated without causing damage. A humidity measuring sensor is located within the stack to provide an initial value (1) of the inherent humidity of the timber. A processor, operating as a drying regulator, interprets the measured value to produce a controlled humidity characteristic (2). The sensor provide continuous feedback of actual humidity so that the temp. (4) and humidity (5) rates are set automatically.

Title: Metal bar straightening process - clamps bar at two points, and displaces one clamp point
Inventor: WUENSCH ADOLF
IPC: B21F1/02
Filed: 1979-09-05
Abstract: The process is for the straightening of metal bands, pipes, or bars, before subsequent punching and/or bending, the metal being intermittently fed into a cutting/bending appliance. A metal bar (10) etc. is clamped at two points, at a certain relative distance, during a working cycle of the bending appliance which takes place between two advance cycles. The clamped length of metal is then stretched, by linear displacement of one clamp point (20), and by exceeding the elastic deformation range of the metal. The appliance has two clamp units (18,20), with actuating units, one having a drive for displacement.

Title: Induction welding of rings onto valves for IC engines - via automatic machine using jigs to assemble valve and ring, and to rotate valve during welding
Inventor: DUDKO DANIIL ANDREEVIC
IPC: B23K31/02
Filed: 1979-12-28
Abstract: Machine includes a horizontal jig (6) into which a ring (33) rolls via gravity via a shute (5). A valve (34) slides down a second chute (4) so its shank enters ring (33).

Title: Multi-chamber hand spray tin - uses separate guide paths from suction tube in separate chambers to nozzle
Inventor: DAUBNER GERHART
IPC: B05B11/00
Filed: 1980-03-14
Abstract: The multichamber hand spray tin is driven either manually or mechanically. It permits the spraying of completely different spray substances through a suction pressure pump. This is made possible by separate spray substance guide paths provided from the suction side right up to the nozzle. The pump has several different nozzles which adjust to the spray materials being sprayed. This allows atomisation e.g. of a liquid and a dry spray material from one container with several chambers.

Patent DE-3030956-A1 (DE)
Title: Oil slick absorber of peat made hydrophobic - by treating with cationic dispersion and/or pref. organo:polysiloxane(s)
Inventor: ROESSLER ERICH
IPC: C02F1/68
Filed: 1980-08-16
Abstract: Substrate oil absorbency is increased by employing peat soaked with a hydrophobically active substance in the form of cationic, aq. dispersions; drying is then effected. Pref. dispersions based on cationic emulsifiers are used, i.e. those contg. basic Al, Ti or Zr salts. More pref., cationic emulsifiers are used which contain organically fixed nitrogen. These can, more specifically, contain cpds. produced from the reaction of diamines or polyamines with epoxy gps. Such dispersions may employ the prods. of a reaction between urea and its derivs., with epoxy gps. Quat. ammonium cpds. may be included in dispersions. Alternatively, organopolysiloxanes can be crosslinked to provide the hydrophobic cpds. by applying crosslinking agents and/or curing catalysts. Accordinly, alkyl hydrogen polysiloxanes can be used in association with curing catalysts, e.g. organic cpds. of tin. The most. pref. peat is white peat. Peat treated in this way can absorb 8-12 times its wt. of oil. The organopolysiloxanes absorb the oil partic. rapidly, following which the impregnated peat that has absorbed the oil floats and can be skimmed off. Peat is more economical to use than other substances in soaking up spilt oil which, if left untreated, poses a threat to the environment, even in small amts., partic. to water supplies. The residual, oil-soaked peat can be used as a fuel.

Title: Precision probe, in particular as a displacement sensor
Inventor: KUCHENHART FRIEDRICH-WILHELM
IPC: G01B7/02
Filed: 1981-01-28
Abstract: The invention relates to a precision probe, in particular as a displacement sensor for length-measuring devices. The invention provides a probe which can be inserted in the most restricted space, e.g. in a measuring mandrel. The aim in this case is to achieve undisturbed transmission of the motion of the probe onto a spiral spring which is aligned with strain gauges without the transmission of lateral forces, torques or bending moments. This is performed by the special design and arrangement of the probe, e.g. as a ball and/or in a probe insert which is guided in a preferably sliding fashion between stops and touches the free end of the spiral spring only in a punctiform manner. <IMAGE>

Title: Process and apparatus for winding up a layflat tubular film web of plastic to form a coil
Inventor: HALTER HARTMUT
IPC: B29C48/10
Filed: 1981-02-11
Abstract: The invention is based on a process for winding up a layflat film web of plastic, produced in a blown-film installation, to form a coil from a multiplicity of film turns. The film web of plastic, drawn off at a predetermined constant drawing-off speed from the blown-film installation, is wound up in accordance with the drawing-off speed and, before winding up, is subjected to a periodic gauge equalisation. This is performed with the aid of a gauge equalising unit, which is moved at a laying angular rate on a laying circle of a predetermined radius and which describes for each film turn onto the coil a laying sector related to the laying circle. This laying sector represents the product of laying angle rate, laying circle radius and winding-up time for the film turn concerned. In order to achieve coils of a completely circular-cylindrical outer surface, during winding-up of the film web of plastic, the laying rate is reduced in accordance with the increasing winding-up time for the film turn, to be precise in such a way that the laying sector is kept constant for a multiplicity of turns. An apparatus for carrying out this process has a pulse generator, which generates a control pulse in accordance with the number of film turns and/or in accordance with the thickness of the coil. The control equipment is further designed in such a way that the control device of the equalising unit drive can be controlled to maintain a constant value of the laying sector. <IMAGE>
